After each pipe-full of tobaccov a smoke cooling chamber i5 of considerably enhas been consumed, the accumulated oils and larged diameter adjacent the inner end Of the y i juices in the condensing' chamber are easily disbit. kThe inner end of, the bit is Aominterbored at charged by'simply disjoint-,ine tnebit from the Iii t0 accommodate a lining il which is inserted 5 Il;` shank of the pipe and pouring the liquids out of under heat ,and pressure `and is frictionally held trated in Fig. 1. The inner end of spout 20, comprising the inner terminus of smoke cooling f chamber I5, is flared or funnel-shaped as illustrated at 2l for the purpose of facilitating the continuous drainage of saliva or moisture froml the cooling chamber into the condensing cham-` ber 5 as described below.

In the pipe described above and illustratedin Figs. l and 2, the tobacco smoke is condensed l' in the long chamber 5 in the shank of the pipe,

thereby removing nicotine oils and tars, which are trapped therein. 'I'he smoke thus cleansedl of impurities then passes through the spout 2l!` into the chamber I5 where the smoke is cooled before being drawn into the mouth. In order to accommodate the great majority of lsci-called we smokers, who permit saliva to drain into the bit, the funnel 2i with its projecting spout20 allows salivato drain through 'the channel in the bit end of cooling chamber I5 and into. the

condensing chamber 5, where it is trappedwit'h the oilsand tars and held for removal.v When the pipe is being smoked, the bowl I is` almost always in a position lower than the bit in the mouth, thus allowing the `saliva to drain through the funnel and into the .condensing chamber. Also, the pipe is occasionallyremoved from the mouth and most smokers in doing so, ltipl the bowl downward, so that the pipe while being smoked if often tilted into a position which permits the saliva to drain into the condensing chamber 5 from which it is prevented from re' entering the bit and .the mouth-becauseof the appreciable'space between the wall of condensing chamber 5 and the spout 2D.

' After each pipe-full of tobacco has been con?v sumed, the liquids in condensing chamber 5 are easily discharged by simply disjointing the ybit I while holding .same pointedslightly upward, and pouring the liquids out of' the condensing chamber. 'To facilitate pouring, the' outer end of sleeve 9 vis tapered to a sharp edge as illus#V trated at 22, which is adapted -to' abut against the wall of liner I1 when' the'bit and' stem'are assembled as shown in Fig. 1'.

or oftener as occasion requires, by inserting'th'e blunt end of a pipe cleaner bent double and swabbing the side walls of the chamber around the tube 8.

Fig. 3 the sleeve 9 is provided with an integral extension 24 which completely lines the wall of the condensing chamber 'and has an end Wall 25 providedwith a hole Which registers with the .i vl'bore 1 at the bowl end of the pipe and is just large enough to admit the tube 8, the shank of the pipe being otherwise similar to the construction shown in Figs. 1 and 2. y In this form of the invention the condensing chamber, being completely metal lined, will prevent the oils and tars and other moisture from vsoaking into the.

brier of the shank 3. Also, since this metal chamberl is somewhat cooler thanv the ycorresponding chamber in Figs. 1 and 2, it will cause a greater v The bit employed with'Y this pipe may be and preferablyis exactly likethe bit shown toA the right of Fig. 2; although,

-if desired, it may omit the' coolingchamber and be lprovided simply with 'an `internally threaded sleeve 2E ,cooperatingwith the sleeve 9 in thel shank and with a spout 21 in alignment with the borel I4 of the bit and'adapted vto'project into the condensing chamber in linefwith the g-tube 8.

In the embodiment of the invention shown in Fig. 4, the shank 3 of the pipe has a cylindrical condensing chamber 5 similar to that shown in Figs. `1 and 2 except that it is of llarger diameter.l y lThe bit, however, is provided with a plug end 29 forming'a tenon telescoping in the open end ol"` the shank 3, vinstead, of beingv screw-threaded as in the other forms of the invention. Thek smoke I cooling chamber I5 is extended through the plug end of the bit, and a moisture draining spout oi funnel 3 is fitted into this end of the cooling chamber and held therein by friction.

In thisy form'of the invention, as in those previously de scribed, the oils, tars andother liquids trapped in the condensing chamberA 5 are easily removed` after each' smoke 'by simply withdrawing the bitrv and tipping the shank of the pipe downward. It

is unnecessary to shake the bit since thefunner 30 drains all the moisture from the cooling charnber I5while smoking and prevents moisture from reentering the cooling chamber.

It is to be understood that various changes may be .made in the details of construction herein `shown and described' without .departing from the scope vand 'spirit of the inventionas' defined in the appended claim` The inventionjclaimed is: A separable pipe stem having a trap chamber therein, comprising av tube :having a cylindrical inner wall terminatingin 'a iianged portion hawv r ingwall surfaces at substantially right angles toY the cylindrical wall, and a tubular lining element for Saidbhamber, one end ofjsaid lin-ingelementl being removably engaged against said flanged portion, the outer wall of said lining element.

being tapered to said end wherebyto provide-a pouring' edge, `the tapered'wall and the inner cylindricaliwall providinga Yclosed chamber, the' walls of which are `inaccessible to the liquids within the trap chamber;
